PIVOrTED-TONGUE BUCKLE.

To all 'whom t may concern.' Y

' Beit known that l, EMIL HARTMANN, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented a certain new and useful lmprovement in Pivoted-Tongne Buckles, of which the following is a full, clear, and exact description. Y s

y The invention-consists of -a buckle having a] frame with side flanges and inside pivot bearings, and a tongue pivoted in these bearings beneath the frame and slotted for the passage through itv of the strap' to be fastened and so vdisposed with relation to the adjacent end of the frame as to grip `the kstrap between the edge forming theinner boundary of the slot and the adjacent inner edge .of the nearer'end bar ofthe frame, the

tongue at all times ofuse being substantially within the boundary lines of the frame, as

- I will proceed now more particularly to set `4 forth and claim.

In' the accompanying drawings, illustrating theinvention, inthe several figures of which likeparts are similarly designated, Figure l is a top plan view.` Fig. '2 is a bottom plan view. Fig. 3 4is a longitudinal section. Fig. 4 isa longitudinal section with the straps in position, ofuse. Fig. 5 is a partial side elevation, 'and Fig. 6 is a partial longitudinal section, showing the pivoted tongue hanging down, as it does Vwhen unsupported. Fig. .V7 is a top plan view of the pivoted tongue detached.

The buckle frame may be of any approved design, and in the present illustration it consists of the side bars l, end bars V2 and 3,'

and the cross-bar 4, the latter preferably being depressed so as to receive the anchoring strap 5 as shown in Fig. 4, without any undue projection from the buckle. The sides l are made with the backwardly extending longitudinal flanges 6.

Pivot bearings 7 extend backwardly fromv the inner edges of the sides l, andthesc bearings are perforated transversely to receive thelpivots or journals 8 of the pivoted tongue 9. This tongue is made with a transverse opening or slot 10, having a substantially straight vstrap-gripping edge 11, and a backwardly turned finger-piece 12.

The pivot bearings 7 in a' preferred con-V struction are of substantially the depth of i Speccatoncf Letters Patent. Application filed August 26, 1912. Serial No. 717,143.

raten-ted sept. s, isis.

the side flanges 6, or of no greater depth than these side flanges, so as to avoid any projection from the back of the buckle.k

These pivot bearings are located between the cross-bar and the end bar 3.

The pivoted tongue has its greatest width slightly less than the distance between the side' flanges, andV so as to fit easily within these side flanges when the buckle is packed and also when it is in use. The tongue is cut away between the widest portion and the pivots 8 so as to `swing 'clear' of the pivot bearings, and, as shown in Figs. 5 and 6, this tongue hangs straight down from its bearings when otherwise unsupported.

The relation of the edge Vl1 of the tongue andthe adjacent edge 13 of the end bar 3 is such that, as shown in Fig. 4, when the end 14 of the strap to be fastened, is passed up from the back ofthe buckle through the opening or Vslot 10 in the tongue and over the tongue toward the other end of the buckle, the strap will be grippe-d between these edges. The vfinger-piece or finger-hold yl2 puts a bight in the strapwhich serves to accentuate the hold of the tongue on the strap, as indicated inkFig. 4. It is to be noticed, also, that the tongue is arranged wholly at the back' of the frame and is wholly within its outlines or profile; that the adjacent edges 1l yof the tongue and 13 of thek frame come very close together, the former just below thelatter and nearer the n transverse center of the frame, thereby insuring the gripping of the strap no matter how thin it may be; and'that while the hold on the strap is strengthened by increase of strain, the tongue' responds instantly to the slacking ofthe strain when it is desired to release the strap.

VBy the construction described, a very' simple and efficient pivoted` tongue buckle is provided, in which the strap ends may be secured without any material projection;

or, in other words, in a fiatV and sightly manner. As compared with buckles having sliding f tongues, this pivoted tongue moving on fixed points and in an arc of a circle, has little or no tendency to wabble, and cannot tilt from side to sidek and throw and must come up true to the adjacentend the free strap end out of line, but it doesV l its Width; and further itis very easy to thread, thus adapting the buckle in a special manner -for use on Wearing apparel.

Vhat I claim is l.VK A pivotedV tongue buckle, having a frame With sides, side flanges, and end bars, pivot `bearings extending backwardly from the inner edgeV ofthe sides and adjacent to one end bar, and a tongue arranged at thel boundary of said opening coperating with.

the inner edge of said adjacent endI bar to grip the strap between'the tongue and said inner edge of said en'dbar.

21. A pivoted tongue buckle, having a frame with sides, side flanges, end bars, and

adepressedcross bar to which the strapV is -est the adjacentend bar of the frame 'for the passage of the strap to be fastened, the edge on the tongue forming the inner boundary of said opening coperating With the inner edge of said adjacent end bar to grip the strap between. thev tongue and said innerl edge of said end bar.

In testimony whereof I have hereunto `set my hand this 24th day of August A. I). 1912.
